Blackjack Advisor

Dalamud plugin: optimal-play advisor + gil tracker for FFXIV player-run blackjack (the /random 1-13 variant where 10/J/Q/K = 10 and Ace = 1/11).

Because every draw is an independent uniform /random 1-13 with nothing removed, the card value distribution is exactly an infinite-deck shoe (A=1/13, 2-9=1/13, 10-value=4/13). So the best move is computed by exact expected value — no strategy tables, no card counting, deck size irrelevant. The engine (Strategy/BlackjackEngine.cs) is validated against published H17 dealer bust rates and Wizard of Odds infinite-deck EVs.

Features

• Enter your hand with card buttons (or a bare total for dealers that only announce numbers).
• Shows the recommended move, the EV of every option, and a one-line reason.
• Configurable rules: dealer H17/S17, double-after-split, and whether the host offers double/split.
• One-click buttons to say your move in chat — only when you press them, never automatic.
• Live gil session tracker (net since session start, read from inventory) + manual W/L/P.
• Auto-fills your hand + dealer up card from the dealer's chat on your turn (toggle in Rules).

Build

DALAMUD_HOME=~/.cache/dalamud-dev DOTNET_ROOT=~/.dotnet \
  dotnet build BlackjackAdvisor/BlackjackAdvisor.csproj -c Release -p:Platform=x64

Deploy: bump <Version>, then publish-plugin (or ./publish.sh). Command: /bj.

Needs in-game verification (compiles ≠ works)

• IChatGui.ChatMessage handler fires and Message.TextValue contains the card glyphs (♣♠♦♥).
• Chat auto-fill: ownership gating (turn header / name-prefix vs ObjectTable.LocalPlayer.Name), glyph parsing, and the total-only fallback, against real dealer macros (they vary).
• ECommons.Automation.Chat.SendMessage actually posts to the chosen channel.
• Gil reads correctly via InventoryManager.Instance()->GetInventoryItemCount(1).
• ImGui layout/readability in the live client.

Auto-fill limitation

If a dealer prints neither turn headers (... 's Turn ...) nor name-prefixed hand lines (<Name>, your hand is ...), a generic "Your Hand is:" line can't be attributed to you, so it won't auto-fill. Manual entry always works. See chat-samples.md for the formats handled.
